ELECTRIC PAIN'I REMOVED'.

Application led lai-oh 29, 1927. Serial No. 179,308.

This invention relates to new and useful improvements in an electric paint remover for removing paint lfrom buildings, automobiles, carriages or other surfaces and consists in the novel features of construction, combination and arrangement of parts illustrated in the accompanying drawings and more particularly pointed outl in the appended claim.

In the accompanying drawings which are for illustrative purposes only and are therehard rubber fore not drawn to scale:

Figure 1 is a side elevation of an electric paint remover embodyingmy improvements.

Figure' 2 is a vertical transverse section taken on line 2-2 of Figure 1.

Figure 3 is a horizontal section.

Figure 4 is a central vertical longitudinal section, taken on line 4 4 of Figure 3 and Figure 5 is a detail transverse section, taken on line 5 5 of Figure 2. q

Referring to the drawings for a more particular description of my invention and in which drawings like parts are designated by like reference characters throughout the several views, the numeral l indicates the porcelain heating unit retainers, 2 the back faces thereof and 3 porcelain spacing blocks arranged with their inner ends engaging the back faces of said heating unit retainers.

The numeral 4 represents' the coil wire heating units, 5 the ends of the heating units leading to the terminal jacks, 6 two openings through porcelain for coil mountings, 7 two holes countersunk to a suitable depth in back of the heating unit retainers, 10 two holes counter-sunk to a suitable depth in front of said retainers and 11 zi g-zag grooves for the heatin unit coils.

Thenumera 12 designates an aluminum shell of suitable dimensions for the orcelain heating unit retainers and 13 as stos strips. The numeral 14 designates bolts and 15 brass jacks. '16 represents mica washers and 17 strips of mica used to hold the coil wire heating units in place. The numeral 18 designates slots extending across the porcelain retainers Ato secure themica stri s and 19 plugs with brass bus ings to suit jacks. 20 denotes a flexible cordl wire with standard socket and 21 handle brackets.

-22 indicates a round wooden handle and 23 extra heavy mica plate which fits over the heating units.

-In carrying out my invention, the handle brackets 21 are formed with outwardly bowed intermediate portions 24 and straight flat inner end portions 25 which fit on the top or back of the aluminum shell or casing 12 and are held in place by the heads of the bolts 14. Washers 26 are mounted on the bolts 14 between the outer ends of the spacing blocks 3 and the asbestos strips 13 with the result that a rigid connection may be made between the handle brackets and associated parts without breakin the porcelain spacing blocks or the porcelaln heating unit retainers. The shell or casing 12 is also formed in one side wall with a plurality of transverse vent openings 27 to let out any dead heat that would otherwise accumulate. This will materially prolong the life of the asbestos and insulation without affecting the heat applied to the working surface. At the same time, the handle and parts nearest the hand of the operator will be much cooler than would otherwise be the case.

It is to be understood that in constructing this device, the parts may be of any suitable size or dimensions and any desired materials used.

From the foregoing description taken in connection with the drawings it is thought `that the construction,

vantages of my invention will be readily understood without requiring a more extended explanation. l

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

In a device of the character specified, a hollow shell or casing, porcelain heating unit retainers mounted therein, said retainers provided in their outer or front faces with reversely extendin grooves, coil wire heating units arrange in said grooves, spacing posts arranged with their innerends bearing against the back walls of said retainers, asbestos strips fitting against the back wall of the shell or casing, washers interposed between the asbestos strips and spacing posts, handle brackets, fastenin bolts extending through the inner ends o the handle brackets, the asbestos strips, the washers, spacing posts and heating unit retainers, and electrical connections used in' association with said heating units.

In testimony whereof he aflixes his sig- WILLIAM MULTHAUP.
